In data center networks, group communication is now playing an important role and multicast communications have been expected an effective way to support group communication for large number of virtual machines. Layer-2 congestion control named QCN (Quantized Congestion Notification) is now proposed for supporting high reliability required by LAN/SAN integration in data center networking. When original QCN is simply applied to multicast communication, a multicast sender may receive congestion feedbacks from multiple bottleneck locations on a multicast tree. In this situation, a multicast flow may suffer lower throughput than unicast flows going through the same bottleneck location(s). In this paper, we propose a new layer-2 congestion control for multicast traffic, QCN with Bottleneck Selection (QCN/BS). In QCN/BS, the switch in the worst congestion level is selected and transmission rate of a sender is calculated only by feedback information sent by this selected switch. Our simulation results show that a multicast sender of original QCN can have severely unfair(less) throughput compared with a unicast sender and our proposed QCN/BS completely resolves this unfair problem. |
